PARIS — The man charged with reviving France's shrinking economy and attracting businesses to invest here is gaining a reputation for doing the opposite.

As the country's first-ever minister for industrial renewal, Arnaud Montebourg has told the world's largest steelmaker it is not welcome in France; exchanged angry letters with the head of an American tire company he was supposedly wooing; and scuttled Yahoo's offer to buy the majority of a video-sharing website.
